ELECTRlC-RAI LWAY MOTOR-CAR.

SPECIFICATION formingpart of Letters Patent No. 439,584, dated October 28, 1890.

Application filed October 1 7, 18 8 9.

To aZZ whom it may concern:

Be it known that I, EDMUND VAGEMANN, a subject of the Emperor of Germany, and a resident of Little Rock, county of Pulaski, and State of Arkansas, have invented certain new and useful Improvements in Electric-RailwayMotor-Gars, (Case 6,) of which the following is a specification.

My invention relates to the mechanical construction of an electric car for especial use on what is usually called the horse-car track, the invention embracing and relating particularly to the truck of the car.

The object of the invention is to provide a simple and effective construction of truck in such a manner that an armature or armatures and field-magnets may be a unique part and portion of the said construction. The elements of the construction are so combined as to form what may be termed an electric car truck. Without a model it is difficult to set forth the exact construction 011 paper; but by representing different rectangular and see tional views of the device and illustrations of the several parts by themselves, as is done in the accompanying drawings, it is thought that one versed in the art will be able to build the truck correctly. The figures are described seriatt'm below.

The type of car to which my invention has especial reference is the one known as the John Stephenson type. By slightly modifying other types myinvention may be made applicable to the same also.

In Figure l, beiu g a side elevation, a portion of the car-wheel on one axle is broken away, and also a part of the field-magnet support is shown in section, reference being had to that field-magnet nearest the wheel, which is represented as broken partly away. In order to bring the figure within the limit of the available space on the sheet, the truck is broken midway between the two pairs of wheels and the wheels brought closer together than they would be in practice.

Fig. 2 is a view of a portion of that construction shown in Fig. 1 as it would appear from the opposite direction at a standpoint about midway between the rails of the track orbetween either pair of wheels on the axles,

the section being made perpendicular to the Serial No. 327,380- (No model.)

axles. The field-magnet armature and commutator of a motor show in this figure.

Fig. 3 shows the under part of the truck,

'the view being taken from the track-bed upward. It is as if a man were on his back on the track and looking upward. Fig. 3 shows particularly the exact way of supporting the field-magnets and the exact shape of the fieldmagnet pole-pieces.

Fig. & is a longitudinal view of the fieldmagnet core and pole pieces on the ends of the said core, the view being in section through the axis of the coil.

Fig. 5 shows the pole-piece of one field-magnet, a section of the ear-axle at right angles to the axis thereof, and the lower half of the flange of the core of the field-magnet. The View is in the direction of the length of the axle.

A modification ot the invention is represented in Figs. 0, 7, 8, and 9.

The device embodying my invention in all its details consists of the combination of a car-body a, supported upon the beams c of a truck, and the rods (1, connecting the opposite ends of the said beams to the box-bearings c, which support the car-axles f; the rods g, connecting the said box-bearings, all the tie-rods tending to strengthen the box-bearings in reference to the said beams; field-magnets consisting each of an iron-tube core h loose upon and surrounding the axle f, provided with flanges 1' upon each end and with pole-pieces upon each flange, being connected thereto by bolts passing through holes in the flanges and pole-pieces, the said tube being the core of a coil wound upon. the outside; projections j upon the outer portions of the same and having holes through which pass rods Z, resting upon and suitably fastened-forinstance, by rings m-to the tie-rods (Z and g, as seen in Fig. l, or resting undersaid tie-rods and fastened thereto by said rings, (see Fig. 2, where the rods Z pass underneath the rods (Z and the said field-magnets being supported by the said rods (I, g, and Z; the pole-pieces each being semicircular and embracing within a hollow part of itself one-quarter of the total surface of the armature upon the upper part, and opposite the wheel to which the armature in each case is attached by means, for

' weight. I wheel, the car starts rapidly, although graduinstance, of bolts 11; the'pole piec'es "being lettered 0; commutators 10 upon each axle in pairs and within the ring-armature, where they are provided with brushes supported by brush-holders r, and a handle s,attached to the brush-holder and projecting downward,where it is not in the way of the pole-piece in each case and where therefore it can be easily manipulated.

The invention does not include any particular manner of connecting up the electric cir cuits with the armatures or field-magnets; nor does it involve any new form of armature, any ring type being applicable. Consequently the details of construction of the armatures are not shown; nor are the circuits represented, avoiding thereby confusion in the drawings. The cores of the field-magnets are necessarily long between the armatures; but this is not a disadvantage. I prefer to make them as long as the axle minus the space occupied on the axle by the armatures and wheels. The space between the axles and the inner surfaces of the tube-cores it need not be as great as in the figures, as it is only required that the wheels may rotate without the axles f touching the cores. It is evident that as the armatures are attached to the wheels of the car and the field-magnets are fastened to the tie-rods, which in turn are secured to the truck, the relative motion of the armatures and field-magnet poles are such that the former rotate with the wheels and the latter are stationary with respect to said armatures.

One of the important though not absolutely necessary parts for operation is the fact that the sleepers t are of soft iron. It will appear that there will be a magnetic circuit from one part of the armature-the upper part, for instance-through the wheel to which it is attached,through the iron sleeper on which the wheels may rest, then through the other wheel and upper part of armature on the opposite end of same axle, and then through the whole field-magnet, the armatures serving to close the said circuit except for small air-space. The armatures in each instance being really a part of the wheel, the power of driving the car is applied right at the wheel itself, so that motion does not first have to be applied to other masses either of little or great An armature being applied to each ally. It is evident to those versed in the art that there need not be four commutators,but that there need be but one on each axle. The one commutator and brushes will serve for two or more armatu res.

In the modification in Figs. 6, 7, 8, and 9 the spokes u of the car-wheel 'v are connected at points between the center and the tire of the wheel by arc-shaped arms 00, on which are secured in any convenient manner coils w. The said arc-shaped arms 00 are seen in Fig. 9 without the coils.

I claim as my invention 1. The combination of a car-body, beams lying longitudinally under and supporting said body, two pairs of car-wheels and axles therefor and fixed thereto, box-bearings fastened to the said beams, tie-rods connecting said box-bearings, and other tie-rods connecting thesaid bearings to the extremities of the said beams, cylindrical ring-armatures attached to the inner surfaces of the said wheels and concentric therewith, field-magnet spools or tubular cores surrounding but out of contact with the said axles and provided with pole-pieces on the ends and within inductive relation to thesaid armatures, the said polepieces being rigidly secured to the said spools and carried upon the said tie-rods and within inductive relation with the said armature at its upper portion, means, such as rings, for fastening the said tie-rods to the said polepieces, commutators mounted upon the said axles between the said wheels and the said spools, brushes pressing upon the commutators and provided with handles hanging downward below the axles and within ones reach between said spools and the said armatures, rails for the wheels to run upon, and iron sleepers at right angles to the said rails and connecting and supporting the same, the said wheels and pole-pieces being of iron.

2. In an electric car, the combination of a field-magnet coil, a car-wheel axle passing through the length of the same, pole-pieces to said coil facing the car-wheels, and armatu res within inductive relation to said polepieces and located between the saidiwhcels 4. The combination of a wheel provided with spokes, arc-shaped cores connecting the spokes, and coils upon said spokes, the tire or periphery of the wheel encircling the armature-coils.

5. The combination of a rectilinear and hollow field magnet carried by the car-truck stationary therewith and surrounding the carwheel axle, armatures mounted upon the axle at opposite ends of the said magnet and rotary or movable with the axle, and iron carwheels and iron sleepers completing the mag netic circuit between opposite ends or poles of said magnet.

. In testimony that I claim the foregoing as my invention I have signed my name, in. presegge of two witnesses, this 22d day of August, 1 9.

EDMUND WAGEMANN.
